GASOLENE-FEED CHAMBER FQR CARBURETERS.

' Specification of Letters Patent.

Application filed May 23, 1907. Serial Np. 375,307.

To all whom it may concern:

Be it known that I, GODFRIED J. MAYER, a citizen of the United States, and resident of Buffalo, in the county of Erie and State of New York, have invented certain new and 1 useful Improvements in Gasolene Feed Chambers for Carbureters, of which the following is a specification. i I

This application is a division in part of my application Serial No. 353,713, filed J anuary' My invention relates to gasolene-feedchambers for carburetors; and its objects are, the production of simple and effective means for regulating the supply of gasolene to the carburetor; to provide an improved gasolene strainer which by reason of'its arrangement affords an extended surface considerably larger in area than the cross-sectional area of the passage in which it is situate'd; to provide improved means for re- .1. Fig. 4 is a central vertical section taken at right-angle to that shown in Fig. 3. Fig. 5 is a horizontal section taken on line 'z -'2, Fig. 4. Fig. dis a detached perspective view of the float retainer-clip.

Referring now to the drawings in detail,

like numerals of reference refer to like parts in.the several figures.

The reference numeral 7 designates the ,chamber having an inlet passage 8' for gaso-' lene or other like fluid cored'through a boss 9 on thebottom of the chamber. Withinsaidpassage I place a sleeve 10 beveled off at its strainer 11 than could be used if the sleeve.

inner end to provide, space for a larger were cut off square. Opening centrally into the chamber through the bottom thereof is an inlet opening 12; the bottom being slightly elevated around this opening to prevent any sediment accumulating therein so that this opening is always unobstructed, and

ings which are located axially in the justed thereon. The stem is Fig. 3 is'a censurrounding said 0 eningon the underside pf the bottom is a va ve seat 13'. Beneath said inlet opening, the boss 9 is tapped for a screw plug 1 4, the purpose of which will'presently appear.

The top of the chamber is closed by a cover 15 which has an annular externally threaded flange 16 for engagement with the internally threaded upper end of the cylindrical wall of the chamber. Said cover also has an opening 17 alined with the inlet opening 12, and a stem 18 is introduced throu h the tapped opening of the boss 9 closed by the screwp ug 14 and is guided-in said alined oppnottom and cover of the chamber respectively.

' The lower portion of said stem is angular in cross-section so that the gasolene may pass upward into the chamber through the inlet opening, and at its lower extremity it is rovided with a'spherical enlargement 19 w ch acts as a valve to close said inlet opening. The closing of said 0 ening is controlled by a float which may wel be made of cork and it referably has a tube 20 axiallythrough its body through which the stem 18 is passed; said tube being preferably of metal so that the float or buoyant body may be easily adprovided with a series of notches 21 preferab y in the form of. annular grooves with which a retainingdevice 22 is adapted to engage. Said retaining-device is constructed of s ring wire bent to clasp the stem, said wire eing bent at a point between its ends intoa spring loop 23. which provides the necessary s ring for a second or clasping-loop 24 forme by www- "ing the wire, which is then directed outward in diverging lines to form two diverging arms 25, one end of the wire terminating 1n a loop 26 at the outerend of ,one of said arms, and

curvedinto a loop 27 and the end of the wire inserted into the body .of the float, The

at the outer end of the other arm the wire is loops 26 and 27, aflord convenient means for actuating the retainer-clip, it being merely necessary to draw the free arm of the cli toward the fixed arm, when the loop 24 wi become enlarged. and disengage itself from the valve stem. The float-can then be raised or lowered to the desired position on the stem and upon releasing the free armof the retainer, the loop 24 en ages the stem and retains the float in its a justed position. Surthe valve stem can be agitated in case the I valve atthe lower end thereof shouldstick in the seat 13 or when it is desired toflush the 1 carbureter.

The cover is held against unscrewing by a spring arm 30 arranged vertically on the outside of the chamber; it being formed of spring wire having one end secured in a boss 31 on the cylindrical 'Wall of the-chamber and its other end extending above the cover and recurved to form a stop 32 which has its end in contact. with the cover. A lug 33 is formed on the chamber at theupper endthereof adjacent said spring arm, and when it is desired to remove the cover from the chamber, said spring-arm is sprung outward and laterally to bear against said lug; by so doing,

the stop 32 is moved clear of the cover, which i can then be unscrewed. After the cover is again screwed into position, it is onlyneCessary to force the spring arm over the end of the said lug when it springs in place and locks the cover against unscrewing.

The chamber is provided with another boss 34 having a passa e 35 in connection with the exit-port 36 att e bottom of the chamber, said exit-port being controlled by a needlevalve 37 and the chamber is also provided with a radial boss 38 having a passage 39 nearly at right-angles to that numbered 35 and communicating with the port 36. Boss 38 is internally threadedv to receive the vaporizing nozzle 40 of the carbureter and exteriorly threadedfor connection with the cari In operation the float will be adjusted on thestem so that the gasolene in the chamber will be on a level with the nozzle, and as it is vaporized, the float-controlled valve will au-' tomatically admit more gasolene in a manner clear to those skilled in the art to which this 7 invention a pertains. Having t 1118 described mymventlon, what I claim is,

1. A chamber having a cover removably' adapted to be sprung onto said lug to disenga e said offset portion from the cover and ho d it out of engagement.

2. A chamber having a cover removably threaded thereon and'a lug onits outer face adjacent said cover, a springbar secured at one end near the bottom of said chamber and having its other end extended above the cover, said bar being made of spring Wire bent upon itself at a oint above the cover and terminating in a r e ending stop bearing against the cover and being adapted to be sprung onto the lug on the chamber to disenga e said depending stop from the cover and ho d it out oi engagement.

3. A chamber having an inlet and an outlet, a stem having a valve adapted to close Witnesses.
